The Olympus PEN-F is a mirrorless interchangeable-lens camera in the Micro Four Thirds system, released in 2016.

The PEN-F pays tribute to the similarly named PEN F half-frame 35mm film SLR camera from 1963.

This sensor later found its way into the OM-D series as well, featured in professional cameras like the E-M1 Mark III.
